Abstract (en)
A stereoscopic display system is provided, including a polarization-switching light source and a polarization-preserving projector which is illuminated by the polarization-switching light source. The polarization-preserving projector may form a left-eye digital image and a right-eye digital image, and the polarization state of the polarization switching light source may be changed in synchronization with an alternating projection of the left-eye digital image and the right-eye digital image.
